I STEAM-TURBINE.

Patented Jan. 22, 1907.

To all whom it may concern: H

Be it known that I, SIMON 000K, a citize of the United States of America, residing at East Akron, in the county of Summit and State of Ohio, have invented new'and useful Improvements in Steam-Turbine Wheels, of

which the following isa specification.

This invention relates to steam-turbine wheels; and one of the principal objects of the same is to 'providea turbine-wheel of simple construction, ."which will operate economic.- ally, and which is composed of few parts, and which will operate efficiently in either Another obj ect'of my invention is to pro vide a turbine-wheel which may be. operated by means of steam,water, hot air, or other power and which can. be quickly reversed. to rotate in opposite directions. -I

These and other objects may be attained by means of the construction illustrated inthe accompanying drawings, in which- Figure l is a central vertical section of a turbine-wheel made in accordance with my inventionf Fig. 2 is a transverse sectionlon the line 2 2, Fig. 1. Fig. 3 is a vertical sec Referring to the drawings for a more particular description of my invention, the "nuposed of disks or cylinder heads 2 and an intermediate flanged rim 3, said rim having outwardlyextending flanges 4, which are connected by bolts 5 to the c linder-heads 2-. A base 6 is formed upon t e intermediaterim 3, and at the upper portion of said rim a solid extension7 is formed. Extending tan-.- gentially through said extension 7 are the diverging inlet-openings 8, and connected to the outer ends of said 0 enin s 8' isa branch pipe 9, one branch 0 whic enters one of the openin s 8 and the other branch communicates with the other opening. The inlet-pipe 10 and the branch pi e 9 are connected to a suitable valve 11, y means of which steam or other power may be admitted to either branch 9 through the openings 8 to the rotary piston 12. The piston 12 is extending through stuffing-boxes 14 upon the opposite sides of the cylinder-heads 2, and a pulley 15 is secured to said shaft for a belt to lead to the device to be operated by the turbine. The piston 12 has formed upon its periphery a radially-extending zigzag centhe proj ecting .11 is turned to admit steam-or other tral flange 16, and alternately arranged on opposite sides of said flange are a series of a utments 17, said abutments. being disposed in linewith the apices 18 of the zigzag sections of the flange 16. The exhaustport may be located at any suitable point,

' ut as shown in Figs. 1 and 3 isformed,v

portion 7 of the rim 4, asin- 4 dicated at 19. I The operation of my invention may .be briefly'described as follows: When the valve through the left pipe 10 and through the-pi e9 at piston and rotate said piston from right to era when thevalve is turned to admit steam through the right-hand opening in Fig, 1, the piston 12 is rotated in the op 0- site direction. The abutments 17 being 0- cated' alternately on opposite sides of the piston and in transverse alinement with the a ices .18 of the zigzag flange, the steam is discharged alternately upon opposite sides of said flange against one of the abutments 17, which successively come into position to receive the impact of the steam or other power. From the foregoing it will be obvious that my turbine-wheel is of simple construction,

power 1g. 1', the steam passing-t ough Q I the opening 8 willimpinge a ainst the abutim'ent's 17 upon one side of t e center of the iscomposed of-few parts, which cannot read ilyfget out of order, can be immediately reversed to rotate in opposite directions, can be reduced at slight cost, and can be utilize for many purposes in the arts. w

Having thus described the invention, what I claim is- '1. ;In a turbine-wheel, a casing, a piston i adapted to rotate therein, said piston being provided with a radially-extending zigzag centrally-disposed flange,- and inwardly-extending alternately-arranged abutments.

2. A- turbine-wheel com rising a casing, an intermediate rim extending around said casing between the cylinder-heads, and pro- .vided with outwardly-converging openings,

a branch pi e fitted to said openings, an mlet-pi e, an an intermediatevalve for placing t e inlet-pi e into communication with either of said 'verging openings, a rotary piston mounted in said casing, said piston provided with a zigzag flange, and o po 'sitely-located inwardly-extending a ternately-arranged abutments.

3. A rotary turbine-wheel comprising a cylinder or casing consisting of" cylinderheads, and an intermediate flanged rim bolt Q i -s42,0ss
